AI Chatbots and the Buyer Journey: Why the Same Question Gets Three Completely Different Answers

TL;DR

One search question produces a different search path in ChatGPT, Google and Perplexity. My research connects those differences to the buyer journey: ChatGPT looks for case studies, Google shows sources and Perplexity more often points to comparison sites.

Google still ranked your site number one, but ChatGPT has never heard of you. Sound familiar? You are not alone. Ranking in AI search engines is a new chapter for online marketers, and it is not getting any easier. I investigated whether a search question is related to the answer you receive. The answer is both reassuring and challenging. Yes, there is a pattern. Yes, it is connected to the buyer journey. No, you cannot do the same thing for all three platforms. ChatGPT looks for case studies, Google surfaces more sources, and Perplexity points to comparison sites. The same question, three completely different answers. My analysis of this strategic choice appeared in Marketingfacts: From SEO to GEO: Which B2B content performs in ChatGPT, Google AIO and Perplexity?
